A computer’s software refers to a program (or a bunch of programs) which give a computer directions on what to do and methods to operate. Software programs can provide one predominant task, or multiple important tasks.
For instance, a program designed to edit digital photographs has one key task (i.e. to permit for editing of photos) – naturally it would have numerous sub-tasks although (i.e. red eye removal, colour correction options, resizing and cropping/slicing of an image).
On the other hand, a computer’s operating system (a complex piece of software which basically handles and runs all the pc) would carry out many main tasks – for example dealing with input and output (i.e. the person typing in with a keyword, or audio popping out of speakers), memory allocation, managing the computer’s hardware elements (these are the electrical elements which energy a pc) and far more.
Software might be grouped into roughly teams: application software and systems software. Essentially, software which facilitates just one foremost task (for instance, photo editing software as within the above instance) could be counted as application software. This is contrasted to systems software which refers to complex, multi-task programs which assist to run your complete system – corresponding to an working system.
These most important groups of software are discussed in more detail beneath:
Application Software
This is software which is put in on an operating system (See «Systems Software» under for more information). As mentioned above, this type of software tends to perform just one major task. One other example of application software can be a website browser: this is the program which you’re probably utilizing right now to view this article. Examples of a browser include Internet Explorer, Google Chrome and Mozilla Firefox. In brief, their main task/function is to facilitate you in surfing the internet.
Other types of application software are as follows:
Word Processing – this type of software lets you type up documents and letters. Examples include Microsoft Office Word and Open Office.

Photo Editing – this type of software can be utilized to edit and manipulate photos and other digital images in numerous ways. Examples include Paint.net, Corel PaintShop Pro and Adobe Photoshop.
Systems Software
This type of software is quite accurately described as being on the very core of any laptop system. Without systems software, a computer could not really function. In short, it manages each facet of a pc system – from how the hardware interacts with the software (‘drivers’) to giving the user an interface and platform to work together with the system (‘working system’). The working system – or ‘OS’ – is the software that loads up after your pc is switched on. It’s where all application software is put in on. Examples of an OS include Microsoft Windows (XP, Vista, 7 etc), Linux (Ubuntu, CentOS) and Apple Mac OS X.
Other types of systems software include system drives (these make the hardware components function appropriately with the software and computer system) and utilities (these are also called ‘utility tools’ and they help monitor, maintain, check and analyze totally different parts of a pc; reminiscent of ‘Task Manager’ and ‘Disk Defragment on Windows OSes).
